vTo ALI'J WHoM Mr MAY coNoERN:

Beit knownv that I, HEZEKIAH M. CLARK, .of Cleveland,in the county ofCuyahoga, and State of Ohio, have 1invented certain new and u'sef'ul Improvements in Lauips; and I do 4hereby declare that the following is a full andcomplete' description of the same, reference being had to the accompanying drawings, making a part of this specification, in whichi v Figure l is a sid'e view. Y Figure 2 is a vertical section. j y l Figures 3 and 4 will be referred to in the .deseriptiomf.l

Like letters of reference refer to likeparts in the views. Y y g p In tig. 1, A represents the globe of the Alamp,'which can'belconstruoted with a stand or foot, and the burner attached to the tube B in theordinary way, Athe lamp beingmadeof` any suitable material. This tube B referred i to extends through the globe of the lamp, theend beingclosed, as shown in g.l2,^and being fittedin an opening cut through the under' side of the globe, said tube being. .provided with small openings, awhich will-bev referred to hereafter. Around the opening through which the tube passesare corrugations, `asshown at [finv viig. 3, which is a top view of' the inside-of the globe, Ev E being-views ofi` the fian'ge C. Aroundv the tube B, just above the corrugations, is secured the ange C, which rests on eorrugations, as shown in fig. 2.1 Fig.v

i4 is a modification ot `iig.3, the flange being corrugated, and the bottom-'of the-globe plainandsuioothig-f. '3

.v i l, Y 7, before described, being'the revcrsewthe bottom of lthe globe corrugated, and the ange having a'plam, smooth surface. y'llic'top of this tube is also provided with a lHarige, D, which rests close against the under side of the top of,l the globe, and forming a groove onv each side tothe openings e inthe tube, the purposeoi'which will be described hereafter. l This lamp is provided',.in the ordinary way, with a wick and burner, they wick passing down into the tube B. Theilamp is thentilledfwith oil by pouring it in from the top ofthe tube, whichpassing down, will iill said turbe up to the openings a,riig. 2, and then flow through these openings-,between the corrugations b, into the globe ot thelamp. v l

Itis well known that oil-lamps, when made in the ordinaryway, are very liable to explode, which is caused by a large amount 'ofgas Vaccumulating orgather'ing bet'weeathe oil and'base of thevburner. As this gas which accumulates in the globe comes in Contact with the flame, itv ignites,and thus bursts the lamp, oft-en with loss, of iife, and great dainage to property. With the above-described lainp this danger is avoided, as the space-for this'gas to accumulate `is very s`mallthe wick' being placed. in the tube, as state d,-and the gas that will thusaccninulate, which isl n. veryV smallvamount, is taken` up bythe wick and burned. The gas that collects or rises above the oil in the globe is conducted out freni said globe,`o'ver the flange D, through the openings c, into' the tube, and then consumed with the oil taken tip-by the wick. The gas. thus increases the. light, without' any danger of explosion. Thisv lainp, by being constructed in this way, can` be filled whenburning, the tube in which the gas. accumulates being-so small thatpno ignition will take piace.

What I claim asmy improvement, and desire to secure byLetters Patent, isg l. .i'ihe eorrugations c, in combination with the perforated tube B and ilange C, substantially as and for the purpose sotfforth. i' A 4 2. The grooved flange D, incoinhination with the tube vB and globe, substantially as and for the purpose set forth.4
